Ralph or players at fault is of course a false dichotomy. It is, of course, a combination of both.
Ralph's career is in serious jeopardy, unless he can turn it around. Getting sacked or walking are not a great options for him, the latter almost never happens anyway because you don't get paid off.
The squad has well-documented serious weaknesses but is not as abject as the present performances. Baffling selections and out of position players are a mystery.
